7 Steps to Better Decisions

1) IDENTIFY YOUR GOAL
People that are not self-reflective are going to end up making bad decisions because they don't really know what they want in the first place.
2) ELIMINATE CHOICES BY SETTING STANDARDS
If you are buying digital camera, list the features you'll actually use. Ignore anything fancier.
3) DON'T WORRY ABOUT FINDING "THE BEST"
How good you feel about your decisions is usually more important than how good they are objectively.
4) BE AWARE OF BIASES
They can lead smart people to make dumb decisions.
E.g. we hate to lose more than we like to win which can result in behaviour such as holding on to a tanking stock instead of accepting a loss.
We remember vivid examples better than facts which is why plane crashes stick in our heads more than statistics on air safety.
We are susceptible to how information is framed: a "cash discount" is more appealing than "no credit card surcharge".
Keeping those biases in mind can help you think clearly.
5) TRY NOT TO RUSH
People tend to make poorer choices when they are in a bad mood or under a lot of stress.
When facing a complex decision, use your concious brain to gather the information you need, and then take a break. Go for a walk. Spend half an hour meditating. Take a nap. Have a beer. Give your unconscious mind some time to do its work.
6) DON'T SWEAT THE SMALL STUFF
When possible, eliminate the need for decisions by establishing rules for yourself.
E.g. you will workout twice a week; you will not have more than 2 glasses of wine; you will buy whatever toilet paper is on sale.
7) DO A POSTGAME ANALYSIS
After each decision you make, ask yourself how you felt afterward and what about the experience you can apply in the future.
